Nothing found after lockdown at Hillsborough High

TAMPA (FOX 13) - A day-long lockdown at HIllsborough High School ended with few answers Friday after a mysteriously broken window had Tampa Police trying to figure out if a bullet was responsible.

At about 9:15 a.m., a teacher in a second-floor classroom heard a window break. That prompted administrators and police to put the school on lockdown while they searched for the object that was responsible.

"My understanding is that there was no loud noise or anything like that, the students just noticed that the glass had broken," said TPD Spokesperson Steve Hegarty.

Parents rushed to the school as they received text messages from their kids telling them they were locked down; some students thought there had been a shooting.

"It's very nerve-wracking," said Ingrid Rafael, a mother who waited hours outside the school for an update. "I immediately ran over here and then as I come in, there's an ambulance leaving so I don't know if that ambulance is coming from the school or anything and my stomach is turning upside down."

Within an hour of the incident, Hillsborough County Schools called parents and notified them that there was a precautionary lockdown, but that everything was okay.

Police were unable to locate anything in the classroom where the window broke and decided to search each student to see if anyone had a weapon.
